External Dependency Manager Directly included in Repo instead of included as Package Dependency

[Asanche]

I have a project that is dependent on the https://github.com/googlesamples/unity-jar-resolver package

If I include the arcore-unity-extensions repo, it gives me the following error at build-time

GUID [3aa17cd5f43042a1a7381759dc1258a7] for asset 'Packages/com.google.ar.core.arfoundation.extensions/Editor/ExternalDependencyManager/Editor/Google.VersionHandler.dll.mdb' conflicts with: 'Packages/com.google.external-dependency-manager/ExternalDependencyManager/Editor/Google.VersionHandler.dll.mdb' (current owner) We can't assign a new GUID because the asset is in an immutable folder. The asset will be ignored.

This package should not be directly included in the repo, afaict, and instead included as a package dependency.

Bumping this issue. Was the source of many headaches of trying to perform an iOS build while using the Firebase Unity SDK.

In case it helps, here is a synopsis of the issues experienced and a solution for anyone else who encounters this:

• Firebase Unity SDK .unitypackage files include the External Dependency Manager at Assets/External Dependency Manager. This conflicts with the ARFoundation extensions External Dependency Manager when imported, resulting in the GUID error message above as well as a "Failed to create menu item" error as both managers are trying to add their menu items to the Assets menu.
• Firebase Unity SDK depends on a more recent version of the External Dependency Manager than ARFoundation Extensions - deleting Firebase's version results in the following error on build: MissingMethodException: System.Collections.Generic.IEnumerable'1<string> Google.IOSResolver.GetXcodeTargetGuids(object,bool)
• Deleting ARFoundation's version also breaks the build with a Null Reference Exception in Google.XR.ARCoreExtensions.Editor.Internal.IOSSupportHelper.EnableIOSResolver ().

The solution is to delete ARFoundation's outdated External Dependency Manager and update the _iosResolverGuid variable in Editor/Scripts/Internal/IOSSupportHelper.cs to the GUID found in Google.IOSResolver_{version}.dll.meta of whatever is the more up-to-date version your project has installed. This resolves the Null Reference Exception and after some pods fiddling, I was able to get the build to successfully work on iOS.

Not sure why EDM is included inside the ARCore package, it should be a dependency which is listed on their site. I have been removing this as well for a while.

Any plans on EDM deleting or moving to reference?

At least with Unity 2022.2 in an a new clean project EDM is not even working correctly when included like this. No menu item becomes available and no dependencies get installed, preventing building.
